Have you turned OFF comments on your blog after an unsuccessful fight with spam? If yes, then you can try alternative centralized commenting system ‘Spipra’. Spipra Blog Widget allows bloggers to implement a commenting system on their blog without having to worry about spam.

You need to create an account at Spipra website to use this commenting system. It is a free service and with easy implementation. You need to paste a code to your blog/website template. A separate procedure for Wordpress Blogs is also explained.

After placing a small button or text link on the pages of your site, your visitors will be able to easily leave comments for that particular page. Besides you can also leave comment for a specific webpage on Spipra website itself. For example, check out the screenshot of 3 comments for www.google.com

Less Spam? Since you need ‘Spipra’ login to make a comment, less spam could be the end result. “Flag this post as spam” button is also added to each post. When a post is reported as spam, notification will be sent to a moderator for further investigation.

Interesting service, however adoption could be difficult. Wordpress blogs already has so many anti-spam plugins that work to fair extend. Blogger is not that prone to spam comments.

Being a Wordpress user, an anti-spam plugin will help me more than separate commenting system. How about you?
